Since I updated to Android SDK Tools 25.1.6 and Android Support Repository 32.0.0 (this morning), I got the following error, I didn't change anything in my code and it is still working on my colleague computer (Android SDK Tools 25.1.1 + Android Support Repository 30.0.0).

java.lang.IncompatibleClassChangeError: The method 
     'java.io.File android.support.v4.content.ContextCompat.getNoBackupFilesDir(android.content.Context)' 
     was expected to be of type virtual but instead was found to be of type direct 
     (declaration of 'java.lang.reflect.ArtMethod' appears in /system/framework/core-libart.jar)

     at android.os.HandlerThread.run(HandlerThread.java:61)

Here is a the piece of code that crash:

InstanceID instanceID = InstanceID.getInstance(this); // <-- crash here
String instanceIDToken = instanceID.getToken(getString(R.string.google_app_id),
GoogleCloudMessaging.INSTANCE_ID_SCOPE, null);

It is when I try to get a token from Google Cloud Messaging.

I'm importing GCM in Gradle with splited play-services :

 compile 'com.google.android.gms:play-services-analytics:9.0.0' 
 compile 'com.google.android.gms:play-services-maps:9.0.0'
 compile 'com.google.android.gms:play-services-location:9.0.0' 
 compile 'com.google.android.gms:play-services-gcm:9.0.0' 
 compile 'com.google.android.gms:play-services-base:9.0.0'

EDIT disabling GCM fixed the problem, so my guess is I should migrate to Firebase Cloud Message

EDIT2 My device receive Google Play Services 9.0 (yesterday was 8.4.x). Now it doesn't crash anymore, but complain about module descriptor

 Failed to load module descriptor class: Didn't find class "com.google.android.gms.dynamite.descriptors.com.google.firebase.auth.ModuleDescriptor"
 Firebase API initialization failure.

Does anyone has a similar error, and how to fix it ?

FIXED special thanks to @stegranet. ./gradlew -q app:dependencies --configuration compile helps you to identify what dependencies include SDK 24.x

Main issue is some library import the latest support library using + sign instead of a version. This cause the issue, by including the latest available version.

So avoid + sign in dependencies ;)

I used the gradle dependency tree to solve this error for me.

Just run gradle -q app:dependencies --configuration compile and check the output for entries like this:

+--- com.mcxiaoke.viewpagerindicator:library:2.4.1
|    \--- com.android.support:support-v4:+ -> 24.0.0-beta1 (*)

As Diego Giorgini said this version is too high (>=24). So update the dependencies in build.gradle like

compile('com.mcxiaoke.viewpagerindicator:library:2.4.1') {
    exclude module: 'support-v4';
}
compile 'com.android.support:support-v4:23.4.0'
